Adding a Domino hide-when to a HTML file

Adding a Domino hide-when to a HTML file

Let us say that you have an HTML page on the server with links to various databases within your Intranet. Users login to the server using basic browser authentication to a database called home.nsf. One of the databases is restricted to a group of users. So, you do not really want the other users to see the link. The HTML pages on the server are managed by users via FTP (they have no access to a Domino designer client). So how do we accomplish the hide-when?

The answer is simple:

Create a LotusScript agent in the home.nsf DB called checkUser.js and set it to run as web user. The agent checks the users' group details using an @userNamesList function and then prints a JavaScript function called writeLink(). This will write the link.

Next, in your HTML file (<Head> section) reference the agent as an include for JavaScript: <script language='javascript' src='/domino/intranet/home.nsf/checkUser.js'> </script> The browser thinks it is just a JavaScript text module.

In your HTML file, place a call to the writeLink() function in the place that you want your link to be written.
